what is density?

Question

lol, it kinda slipped my mind to what density was.

Answer 1

Density is, mass per unit volume!

Answer 2

In the simplest terms, it is how heavy a thing is, independant of size, 1 pound of gold is the same weight as 1 pound of feathers, but is more dense, so there's more weight/mass for each little bit of it. A feather made of gold is heavier than a real feather because it has higher density. Density can also be described as how closely packed the particles that make something up are.

Answer 3

Density, or volumic mass (ISO 31), is a measure of mass per unit volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have more mass than an equal-sized object made from some less dense substance (such as aluminium).

Answer 4

In Physics there are many different quantities that are referred to as densities (current density, probability density, etc.). What you are most likeley referring to is the mass density of a homogeneous substance, which is given by the mass of a particular amount of the substance divided by its volume. This quantity is usually reported in g/cm^3 or kg/L, and is sometimes called the specific gravity.

Answer 5

Density is how tightly packed a substance is and it iss expressed as weight per certain volume. if the object has exactly the same desity as the liquid, then its bouyancy equal its weight.

Answer 6

mass per unit volume
